4G Base Station Fronthaul Overall Solution

Overview

A typical 4G base station tower includes antennas, feeder cables, and Remote Radio Units (RRUs). The antennas connect to the RRUs via feeder cables, while the RRUs connect to the Baseband Units (BBUs) located in nearby equipment rooms via fiber optics. Usually, one BBU connects to three RRUs. The 4G base station fronthaul refers to the optical transmission segment between the RRUs and the BBU.

Solution Brief  

FHOLINK Technology's *4G Base Station Fronthaul Optical Transmission Solution* primarily utilizes passive plug-in Wavelength Division Multiplexers (WDM) and 10G colored optical modules to address the optical transmission between BBUs and RRUs. This enables a single BBU to connect to three RRUs, and can even extend to connecting six or twelve RRUs. The solution includes the complete set of equipment from the BBU to the antennas.
